Earth: The Fossil Sun Theory

Earth: The Fossil Sun Theory. A remnant stellar body captured into the orbit of a younger sun



Modern cosmology explains the Solar System as the product of a collapsing molecular cloud, forming the Sun and a rotating protoplanetary disk from which planets accreted. 

Yet there remain unresolved anomalies in planetary composition, orbital resonances, and internal heat distribution that leave room—at least in theoretical exploration—for alternative formation pathways.


One of the more unusual but internally consistent speculative models is the Fossil Sun Theory, which proposes that Earth is not a conventional planet formed from disk accretion, but instead the remnant core of a previous stellar body that cooled, crusted over, and was later gravitationally captured into orbit around the current Sun within a former binary system configuration.


This model attempts to account for several persistent observational puzzles through a single historical reconstruction: that Earth is a stellar remnant object disguised as a terrestrial planet.



1. The Binary Origin Framework

In this model, the early Solar System did not begin as a single-star environment, but as a wide binary system consisting of two stellar bodies:


Proto-Sun A: the current Sun, still in an early main-sequence phase

Proto-Sun B: a lower-mass companion star with a shorter evolutionary path


Binary star formation is common in the galaxy, and long-term orbital instability between stellar companions is well documented. In such systems, differential stellar evolution can produce extreme asymmetries: one star may remain stable while the other exhausts its fusion cycle earlier.


The Fossil Sun Theory proposes that Proto-Sun B did not end in a classical supernova or collapse into a compact object. Instead, due to its lower mass and atypical composition, it underwent a gradual fusion cessation phase, entering a prolonged transitional state between active star and degenerate object.


This phase is critical to the model, as it provides the mechanism by which a star can “cool” into a solid or semi-solid structure rather than collapsing violently.



2. Stellar Cooling and Crust Formation

Standard stellar evolution predicts three end states depending on mass: white dwarfs, neutron stars, or black holes. However, the Fossil Sun Theory introduces an intermediate hypothesis: a low-mass, low-luminosity star entering a metastable cooling regime in which energy production falls below radiative equilibrium but gravitational compression remains dominant.

Under these conditions:

• Outer plasma layers lose energy and transition into high-density ionic matter

• Radiative pressure collapses, allowing stratification of elements

• Heavier elements sink, forming a dense metallic interior

• Silicate-rich compounds crystallize into a rigid outer shell


Over extended timescales, this produces a body with:

A solid crust

A semi-molten mantle

A highly energetic metallic core


In other words, a structure that closely resembles modern Earth.


Within this framework, Earth is interpreted not as a planet that formed cold and later heated internally, but as a hot stellar remnant that cooled externally while retaining internal energetic processes.



3. The Heat Paradox

One of the central points supporting this speculative model is what might be called the heat persistence problem.

Earth’s internal heat budget is unusually high for a body of its size and age. Conventional explanations include:

Residual heat from accretion

Radioactive decay of heavy isotopes

Gravitational differentiation


However, these mechanisms are still actively studied because they do not fully resolve observed heat flow anomalies, particularly in:

Deep mantle plumes

Core-mantle boundary energy transfer

Regional geothermal inconsistencies



The Fossil Sun Theory reframes this entirely. 

Instead of treating internal heat as leftover planetary energy, it proposes that:

The core is not cooling from planetary formation—it is cooling from a former stellar ignition state.

This would imply that Earth’s interior is not a slowly decaying chemical system, but a long-term thermal remnant of fusion-era conditions, now reduced to residual energetic states.



4. Orbital Capture into a Younger Solar System

A key requirement of the theory is explaining how a stellar remnant becomes a planet in orbit around another star.

The binary framework provides a mechanism:

Proto-Sun B enters a late cooling phase and begins losing mass and luminosity

Gravitational balance between the two stellar bodies destabilizes

Proto-Sun A gains dominant gravitational control of the system

The cooling remnant becomes gravitationally bound as a secondary orbital body


Over time, orbital interactions circularize its trajectory into a stable heliocentric orbit.


In this scenario, Earth is not “born” in orbit around the Sun. Instead, it is captured into long-term orbital resonance after stellar system reconfiguration.

This would place Earth in the category of a captured stellar remnant body, rather than a primary accretion planet.



5. Explaining Earth’s High Iron Composition

Earth’s unusually large iron core is well explained in standard models through planetary differentiation. However, the Fossil Sun Theory proposes a different origin:

• Iron and nickel are end-stage fusion products in stellar cores

• Stars naturally accumulate iron-group elements in their final energetic phases

• In a collapsing star scenario, these elements concentrate toward the centre


Thus, Earth’s core is interpreted as:

The preserved nucleosynthetic core of a former stellar body.


In this view, Earth is not differentiated from a primitive rocky mixture, but is instead stratified from a pre-existing stellar element structure, inherited from its prior phase as a fusion system.


This would also explain the extreme density of the core relative to surface materials.



6. Magnetic Field as Residual Stellar Dynamo

Earth’s magnetic field is typically explained through convection in the liquid outer core generating a geodynamo. However, the field exhibits behaviours that remain difficult to fully model, including:

Irregular polarity reversals

Regional field weakening (e.g., South Atlantic Anomaly)

Long-term fluctuations not fully correlated with core convection models


The Fossil Sun Theory proposes that the magnetic field may be partially residual stellar magnetism, a leftover structure from the object's previous state as a plasma-dominated star.

In this interpretation:

• The core retains organized charge flows from earlier fusion conditions

• Magnetic field reversals reflect slow reconfiguration of a decaying stellar dynamo

• The field is not purely generated, but partially inherited


This would place Earth’s magnetosphere in a hybrid category: part active dynamo, part fossilized stellar field structure.



7. The Moon as Crustal Ejection Remnant

The origin of the Moon is typically explained by the Giant Impact Hypothesis. However, the Fossil Sun Theory offers an alternative:

If Earth transitioned from a high-energy stellar state into a cooling crusted body, then periods of structural contraction and instability would have occurred. 


These could produce:

• Massive crustal fracturing

• Ejection of silicate-rich material into orbit

• Coalescence of debris into a stable satellite


Under this model, the Moon is not the result of an external impactor, but a fragment of Earth’s early crustal solidification phase, later stabilized in orbit.

This also explains the compositional similarity between lunar and terrestrial mantle materials.



8. Geological Structure as Cooling Stellar Shell

Plate tectonics remains the dominant explanation for Earth’s surface dynamics. However, the Fossil Sun Theory reinterprets tectonic motion as a secondary expression of a deeper cooling process:

• As internal stellar heat dissipates, the crust contracts unevenly

• Stress fractures propagate along global fault lines

• Large-scale surface displacement occurs as a response to internal shrinkage


In this view, tectonic plates are not floating fragments of a primordial crust, but adaptive stress structures on a cooling stellar shell, adjusting to gradual volumetric contraction over geological time.



9. Why Evidence Is Subtle

If Earth is indeed a remnant stellar body, the evidence would not resemble traditional astronomical remnants like white dwarfs or neutron stars. Instead, it would be obscured by:

• Billions of years of surface reprocessing

• Atmospheric shielding of interior signals

• Geological recycling through tectonics

• Biological modification of surface chemistry


Thus, any stellar signature would be deeply buried in:

• Isotopic ratios

• Core density discontinuities

• Seismic wave anomalies

• Magnetic field irregularities


The theory predicts that such signatures would be ambiguous—compatible with both conventional planetary formation and deeper stellar ancestry.



10. A Reframed Origin Model

The Fossil Sun Theory does not reject conventional planetary science outright. Rather, it reframes Earth as an object that exists at the boundary between categories:

• Not fully a planet in the classical accretion sense

• Not fully a stellar remnant in the white dwarf sense


But a hybrid transitional object formed through binary stellar evolution and long-term thermal collapse.

In this model, Earth’s uniqueness is not accidental. It is structural.


A world that began as light-bearing plasma, transitioned into a cooled crystalline shell, and ultimately became a gravitational companion to a younger star.



Can A Sun Create Water?

In a literal physics sense: no — a cooling star would not create liquid water (H₂O) in the way Earth has it today. 

But it’s worth unpacking carefully, because there are a few different “could it ever happen?” layers hidden in the idea.



1. What a “cooling star” actually is

A star is mostly plasma: ionized hydrogen and helium at extremely high temperatures (millions of degrees in the core, thousands on the surface for even the coolest stars).


Even in the coolest known stellar objects (like brown dwarfs), you are still dealing with:

• High-energy gas, not stable atoms bound into molecules

• No long-lived solid surface

• No stable chemistry in the usual sense


For water (H₂O) to exist, you need:

Stable hydrogen atoms

Stable oxygen atoms

Temperatures low enough for chemical bonds to survive

Usually a surface or atmosphere where molecules don’t instantly dissociate


Those conditions simply don’t exist on or inside any known stellar object.



2. Could a star produce the elements for water?

Yes — and this is another part where the idea overlaps with real astrophysics.

Stars do produce the ingredients for water:

• Hydrogen: existed since the Big Bang

• Oxygen: produced inside stars via nuclear fusion (especially in massive stars)


When stars die, they release oxygen into space through:

• stellar winds

• planetary nebulae

s• upernova explosions


So in a galaxy-wide sense:

Stars are factories for the raw ingredients of water.


But that is very different from producing H₂O itself. They produce elements, not molecules like water.



3. Could a “stellar remnant Earth” form water later?

If we stay inside the hypothetical (“Earth was once a cooling star”), the only plausible route to water would still require a secondary process after cooling, not during the stellar phase.


For example, in that framework:

• The object cools enough for stable atoms to exist

• Hydrogen and oxygen become chemically available in some form

• Volatile compounds begin forming on or within the crust

• Water forms during later atmospheric or chemical evolution


But notice what this implies:

Water would not be a product of the star-phase. It would only appear after the object stopped behaving like a star.


So even in the hypothesis, H₂O is not a “stellar product” — but it is a post-stellar chemical outcome.



4. The real physical barrier: temperature

The key issue is simple thermodynamics.

Water breaks apart at relatively modest energetic conditions:

• H₂O dissociates at a few thousand Kelvin

• Stars are thousands to millions of Kelvin at their outer layers


So in a star-like environment:

• molecules cannot form

• if they do form, they are instantly destroyed


You cannot get stable oceans, vapor cycles, or liquid chemistry inside that regime.



5. What does produce Earth’s water (mainstream model)

The current leading scientific explanation is much more grounded. Water formed from hydrogen and oxygen delivered from:

• hydrated minerals in asteroids

• carbonaceous chondrites

• possibly some cometary contribution


Early Earth was hot, then cooled enough for:

• volcanic outgassing

• condensation of steam into oceans


So Earth’s water is understood as:

a byproduct of planetary accretion + chemical differentiation, not stellar transformation.



6. If we stretch the hypothesis to its limit

If we stay strictly inside the “Earth-as-cooling-star” idea, the most coherent version would be:

• The object begins as a high-energy plasma body

• It cools into a dense, layered structure

• Elemental segregation occurs (H and O become available later in evolution or capture)

• Water appears only after a long transitional phase into “planet-like” conditions


In that sense, water is not impossible in the story — but it is not stellar water. It is post-stellar chemistry on a cooled remnant body.


Bottom line

• A star itself cannot contain or sustain H₂O

• A star can only produce the elements that later become water


Even in a “cooling star Earth” scenario, water would only form after it had ceased behaving like a star entirely.



Final Chapter: Why Ancient Humans May Have Worshipped “The Sun”?

Across nearly every early civilisation, one pattern repeats with striking consistency: the Sun is treated not merely as a light source, but as a central intelligence, a life-giving force, or even a divine ancestor. 

From Egypt’s Ra to the Inca Inti, from Indo-European solar deities to indigenous fire-and-sky traditions, the Sun occupies a position of unusual psychological and symbolic importance.


In conventional anthropology, this is explained in practical terms: the Sun governs agriculture, seasons, survival, and timekeeping. It is the most obvious and reliable celestial body influencing human life, so it naturally becomes sacred.


But within the framework of the Fossil Sun hypothesis—where Earth itself is interpreted as a cooled, once-active stellar body—an alternative interpretation can be explored. Not as replacement, but as speculative layering on top of known cultural drivers.



1. The Cognitive Anchoring Problem

Early humans lived in environments where survival depended on prediction:

When would the seasons change?

When would crops grow?

When would migrations occur?

When would darkness end?


The Sun was the only celestial object that provided consistent, predictable structure to reality.

But in a deeper sense, cognition itself tends to assign agency to dominant environmental forces. Humans naturally interpret:

• storms as anger

• rivers as living entities

• mountains as ancestral beings

• the Sun as intentional presence


This is not irrational in early cognitive frameworks—it is adaptive pattern recognition applied to overwhelming natural systems.

The Sun becomes not just a star, but a structured intelligence-like phenomenon governing life rhythms.



2. A Planet Shaped Beneath a Stellar Memory

If Earth were once a cooling stellar body, as the hypothesis suggests, then its early environment would have been fundamentally different in one key respect:

It would have carried a lingering thermal and electromagnetic memory of stellar conditions.


In this model:

• The core retains residual energetic dynamics from a former fusion state

• The magnetic field behaves as a decaying but structured dynamo

• Heat flux from deep within the planet remains unusually strong and variable


To early humans—who lacked scientific frameworks for geophysics or astrophysics—Earth and sky would not be separate conceptual domains. They would be part of a continuous energetic system.


The Sun above and the heat beneath could easily be perceived as:

• two expressions of the same underlying force


One visible.

One invisible.


One moving across the sky.

One felt through the ground.



3. The Dual-Sun Perception Hypothesis

In a world where environmental phenomena are interpreted symbolically, a conceptual symmetry may emerge:

• The Sun we see is the external fire

• The Earth is the internal fire


Volcanoes, geothermal vents, hot springs, and seismic activity would reinforce the perception that the planet itself is alive with hidden heat and pressure.


If the Earth is imagined—within the hypothesis—as a cooled stellar remnant still shedding internal energy, then early humans would experience a world where:

• fire exists in the sky

• fire exists in the ground

• life exists between them


This structure naturally produces a triadic worldview:

Sky fire (Sun)

Earth fire (subsurface heat, volcanism)

Human fire (domestic flame, survival technology)


Within such a cognitive framework, the Sun becomes not just a celestial object, but the dominant expression of a universal fire principle.



4. Memory Without History

Human cultural memory often preserves patterns long after their original context is lost. Myths can persist for thousands of years, evolving while retaining structural motifs.


If early post-glacial humans inherited fragmented environmental knowledge from earlier populations—whether through oral tradition or cultural continuity disrupted by climate change—then symbolic cosmologies may preserve:

• distorted memories of dramatic environmental transitions (Glacial Melt: Flood of 'God')

• encoded references to unusual sky or geological phenomena

• metaphorical interpretations of planetary-scale processes


Within this speculative framing, Sun worship may not originate solely from observation of a stable star, but from a deeper cognitive association:

The Sun as the surviving visible remnant of an older cosmic condition no longer directly experienced, but still structurally felt through Earth’s energetic behaviour.

This does not imply historical awareness of stellar transformation, but rather symbolic inheritance of a world still perceived as dynamically “alive” in a way modern observers no longer intuitively feel.



5. The Psychological Magnification of the Sun

Regardless of origin theory, the Sun has several properties that make it uniquely suited for deification:

• It is the dominant energy source for surface life

• It governs time through predictable cycles

• It is visually overwhelming compared with other celestial objects

• It appears intentional in motion (rising and setting)

• It is both constant and unreachable


These traits produce what cognitive science would describe as agency attribution bias under high dependency conditions.

In early societies, where survival depended entirely on environmental stability, the Sun becomes:

• provider

• regulator

• judge of seasons

• source of warmth and growth


Thus, worship is not simply religious—it is structural acknowledgment of dependency.



6. Why the “Fossil Sun Earth” Amplifies This Symbolism

Within the Fossil Sun framework, Earth itself contributes an additional layer of reinforcement:

The ground is not inert, but internally active

Heat rises from below without visible cause

Magnetic fields behave as invisible organizing forces

Geological activity reshapes the surface over time


In such a world, early humans would not perceive a clean separation between celestial and terrestrial systems. Instead, they would inhabit a continuum of energy gradients, with the Sun representing the most visible and stable expression.


This creates a psychological model in which:

• the Sun is the external manifestation of cosmic order

• the Earth is the internal manifestation of the same principle

• life exists as an intermediary state between the two


In symbolic terms, worship of the Sun becomes worship of structured life-giving energy itself, regardless of its origin.



7. Conclusion: The Sun as Anchor of Meaning

Whether or not Earth has any unconventional origin history, the persistence of solar worship across cultures reflects something fundamental about human cognition: we organise reality around the most powerful, consistent and intelligible source of energy in our environment.


In the Fossil Sun hypothesis context, this symbolism acquires an additional interpretive layer. The Sun is not only the giver of light and warmth, but the visible counterpart to a deeper planetary system still shaped by ancient energetic processes beneath the surface.


Thus, in this framework, Sun worship can be read as:

• environmental dependence

• cognitive pattern recognition

• symbolic mapping of energy systems

• and possibly a distant echo of a world still perceived as unified in its energetic structure


The Sun endures in human thought not because it is merely seen, but because it represents the organising principle of experience itself.

And in that sense, every civilisation that turned its face toward the Sun was not only acknowledging a star in the sky—but attempting to understand the deepest visible expression of order in a universe still only partially understood.

Point Nemo: The Most Isolated Place on Earth

Imagine standing in the middle of the ocean. There is no island on the horizon. No coastline. No lighthouse. No passing fishing boat. In every direction, land is thousands of kilometres away.  You are closer to the emptiness of the Pacific than to almost anywhere inhabited by humans. This place exists. It is known as Point Nemo — the oceanic pole of inaccessibility — and it lies in the remote South Pacific Ocean. But Point Nemo is more than simply a dot on a map. It is one of the strangest geographical locations on Earth, a place where isolation becomes almost absolute. And, remarkably, it has also become associated with something rather unusual: the final resting place of spacecraft. Where exactly is Point Nemo? Point Nemo lies at approximately 48°52.6′S, 123°23.6′W. According to NOAA, the nearest land is roughly 2,688 kilometres away. Three pieces of land are approximately equally distant: Ducie Island in the Pitcairn Islands, Motu Nui near Easter Island, and Maher Island off Ant...

Why Is England Still Dumping Sewage When It Isn't Raining?

If storm overflows are designed to deal with rainwater overwhelming the sewage system, why are they sometimes discharging when there has been little or no rain? In 2025, England recorded 291,492 monitored storm-overflow spill events. At first glance, that number is shocking. It works out at almost 800 recorded spill events every day of the year. Yet 2025 was an unusually dry year. In fact, the Environment Agency says the fall in sewage-spill numbers compared with 2024 was heavily influenced by those unusually dry conditions. Spill events fell by 35%, while the total duration of spills fell by 48%. So here's the obvious question: If dry weather reduces sewage spills, why are sewage overflows operating at all when it isn't raining? The answer is complicated — and potentially far more concerning than the headline numbers suggest. What is a storm overflow actually for? To understand the problem, we need to look underground. Many parts of England still have combined sewer systems. ...

Could Earth Once Have Had a Completely Different Climate?

We tend to think of Earth's climate as something relatively stable. There are warm places. Cold places. Wet places. Dry places. Ice at the poles. Deserts near the tropics. Forests covering parts of the continents. It feels permanent because human civilisation has existed for such a tiny fraction of Earth's history. But zoom out. Earth is not climatically stable at all. Over billions of years, our planet has moved between conditions that would be almost unrecognisable to us. There have been periods when ice reached surprisingly low latitudes. There have been times when Antarctica supported forests. There have been enormous changes in atmospheric composition. There have been episodes of extreme greenhouse warming. And there have been periods when much of the planet may have been covered in ice. The Earth we know today is only one possible climate state. So how different can our planet actually become? The Earth has never had just one climate Climate isn't determined by temper...

Does Wearing a Mask Affect Facial Recognition? (UK Guide, 2026)

Face masks became widespread during the COVID-19 pandemic, and many people noticed something unexpected: facial recognition systems often struggled to identify masked faces. But in 2026, things have changed. So—does wearing a mask still affect facial recognition? 👉 Short answer: Yes, masks reduce accuracy—but they no longer stop recognition reliably. This guide explains how it works, what has changed, and what to expect in real-world UK use. How Facial Recognition Works Facial recognition systems analyse key features of your face and convert them into a biometric template. These typically include • Distance between the eyes • Shape of the cheekbones • Structure of the nose • Jawline and chin • Skin texture patterns This data is then compared against databases to find a match. What Happens When You Wear a Mask? A standard face mask covers: • Nose • Mouth • Lower cheeks This removes a large portion of facial data—especially areas older systems relied on.

Could Earth Have Once Had a Ring Like Saturn?

Look at Saturn and it is difficult not to wonder what Earth would look like with rings. A vast band of ice and rock stretching across the sky. A permanent feature visible from the surface. Shadows moving across the planet as the ring system changed with the seasons. It sounds like science fiction. But Earth may actually have had something resembling a ring system in its distant past. Not necessarily a beautiful, permanent structure like Saturn's — but a temporary ring of debris could have formed around our planet after a massive collision. And the most intriguing possibility is that such an event may have played a role in creating the Moon. Earth wasn't always the quiet planet we know today The young Solar System was a chaotic place. Planets were still forming. Asteroids and planetary embryos were moving through unstable orbits, occasionally crossing paths. Collisions were not unusual. Some were relatively small. Others were catastrophic. The leading explanation for the Moon...

When Banks Become Landlords, Who Gets Left Out?

For generations, banks have made money from Britain's housing market by lending people the money to buy homes. Now something different is happening. Some banks are beginning to buy and hold residential property themselves. And that raises an uncomfortable question: What happens to house prices when the institutions that finance the housing market also start competing with the people trying to buy the houses? From financing homes to owning them The most prominent example in Britain is Lloyds Banking Group. Through its Lloyds Living operation, the banking group has built a substantial portfolio of residential properties.  Its portfolio has grown to more than 7,500 homes, and in July 2026 Lloyds Living agreed a further acquisition of 980 suburban homes across 14 developments. These aren't simply properties on which Lloyds has issued mortgages. They are part of a residential investment and rental business. That distinction matters. A bank providing a mortgage helps an individual be...

Who Is Really Behind the News You See on Social Media?

Scroll through Facebook, X, TikTok or Instagram and you can encounter hundreds of accounts presenting themselves as news. Some look remarkably professional. Others appear to be little more than a logo, a dramatic headline and a constant stream of political stories. They may call themselves independent media. Alternative media. Citizen journalism. Breaking news. But who actually runs them? Who owns the website behind the Facebook page? Who registered the company? Who are its directors? Who pays for the operation? Who controls the advertising? And are several apparently independent news outlets actually connected to the same people? In an age when a social-media post can reach hundreds of thousands of people within hours, these questions have become increasingly important. And surprisingly often, the answers are publicly available. The brand may not tell you much One of the easiest mistakes to make is to treat a media brand as though it were a person. A page might have a name suggesting ...

GRB 080319B: The Explosion We Could See Across Half the Universe

On 19 March 2008, something extraordinary happened in the distant universe. A massive star died. The event produced an enormous explosion known as a gamma-ray burst, releasing an incredible amount of energy into space. But there was something particularly unusual about this one. For a brief period, the explosion was bright enough to be seen from Earth with the naked eye. The remarkable part? The explosion happened roughly 7.5 billion light-years away. By the time its light reached Earth, our planet had travelled through billions of years of cosmic history. Civilisations had risen and disappeared, continents had shifted and species had evolved — while the light from this distant catastrophe was still making its way towards us. Astronomers named it GRB 080319B. It became known as the "Naked-Eye Burst." A flash from the distant universe Gamma-ray bursts are among the most violent events known to occur in the universe. They are extraordinarily brief, but can release enormous amou...

Did Ice Age Humans Retreat Underground to Survive the Cold?

Could some of our ancestors have spent far more of the Ice Age beneath the surface than we realise? When we imagine humans during the Ice Age, we tend to picture hunters crossing frozen landscapes, wrapped in animal skins, tracking mammoths and reindeer across windswept plains. It's an image that has become almost synonymous with prehistoric humanity. But there is another possibility. When conditions became brutally cold, perhaps the smartest place to be wasn't out on the frozen landscape at all. Perhaps it was underground. Humans have been using caves and rock shelters for hundreds of thousands of years. We know that Neanderthals, Denisovans and Homo sapiens repeatedly occupied caves, sometimes during extraordinarily cold climatic periods. But this raises a more intriguing question: Did some human groups retreat into underground environments for much longer periods during the most severe phases of the Ice Age? The answer isn't as straightforward as it might first appear. W...

What If Consciousness Isn't Produced by the Brain?

You are reading these words. You can hear sounds around you. You can remember yesterday. You can imagine tomorrow. You can feel pain, recognise a face and wonder what it means to be alive. All of this feels completely ordinary. But scientifically, it is extraordinary. Somehow, electrical and chemical activity inside roughly three pounds of biological tissue is associated with the experience of being you. We know an enormous amount about the brain. We can observe neurons firing. We can map brain regions. We can measure electrical activity and watch networks communicate. We can even manipulate brain activity and change perception, memory and behaviour. And yet one enormous question remains: Why is there an experience at all? The brain clearly matters Before going further, there is an important distinction. There is overwhelming evidence that consciousness is intimately connected to the brain. Damage particular brain systems and consciousness can be profoundly altered. Anaesthesia can rev...
